The substance A when dissolved in solvent B shows the molecular mass corresponding to `A_(3)`. The vant Hoffs factor will be:

A

1

B

2

C

3

D

`1//3`

Text Solution

Verified by Experts

The correct Answer is:
D
Van't Hoff factor,
`I = ("Normal mol.mass")/("Observed mol.mass")`
As the solute associates in solution, and gives mass `A_(3) :. i = (A)/(3A) = 1//3`
